New GUI files

the new stuff is all drawn from an example game taken from here:
http://www.gametutorial.net/article/Keyboard-input---Moon-lander

I have started replacing some files to change the look, and added a
course class that we will have to figure out.

The class diagram is also updated to show how the gui works. i added
this gui into my original UML diagram.
